Wästberg grew up in Frillesås on the western coast of Sweden, and played music from an early age, starting with the saxophone at ten. He left his childhood home at 18 and studied jazz saxophone at a Folkhögskola in southern Sweden. After his studies, he performed in a variety of ensembles, and even jammed with Sean Lennon in New York. Ever restless, Wästberg traveled to South Africa, where he spent some time at the University of Kwasulu-Natal in Durban. While there, he became increasingly interested in the Pan-African rhythms he encountered. This fascination deepened as he traveled through Mozambique and Zimbabwe and, emboldened by his experiences, he decided to start making his own music.
The artist recorded his debut record, Digging a Tunnel, between autumn 2014 and spring 2015, playing all the instruments himself. In the run-up to its early-2017 release, sir Was first put out his 2016 EP Says Hi; the set featured the single "A Minor Life," which would appear again on Digging a Tunnel. The material hinted at the multitude of styles and influences Wästberg drew from, incorporating bagpipes, synths, samples, and his own sweet and fragile vocals. Second album Holding on to a Dream materialized in 2019. It was preceded by the release of lead single "Deployed," a collaboration with Little Dragon. The following year, sir Was delivered the EP Letter, while also being diagnosed with a rare genetic disorder. Refocusing his outlook, he started to write his third album, informed by his newly diagnosed condition. Preceding the record, sir Was issued the collaborative EP Marasi with Falle Nioke in April 2021. He finally released Let the Morning Come later that year. ~ Bekki Bemrose, Rovi
